There is another type of cycloidal reduction box you can make that is easier to get backlash-free & easier to fabricate because all the critical machining is groove into planer disk surface. The engagement is axial, not radial. The "rollers" are ball bearings acting between 2 grooved disks. Because of the axial arrangement, backlash can be taken up to compensate for wear or fabrication. 2 facing disks have cycloidal track machined into them: one hypocycloidal, the other epicycloidal. Ball bearings roll between them, held under axial compression. 2 stacked assemblies are used to remove the orbital motion & the difference between the 2 ratios permits large ratios with low lobe counts. A central crank forces orbital motion (same as for drive you have).

@Nedw Ай бұрын

Do you have a link or keywords to find out more about that design of cycloidal reduction box?

@bpark10001 Ай бұрын

@@Nedw Web search gets nothing (I tried "AXIAL cycloidal gearbox). The search latches on "cycloidal" & ignores "axial". I found about this in old optical catalog (for fine motion of optics without backlash). The benefit of this scheme is the ease of making if you have manual lathe & CNC milling machine. All of the "non-circular" elements are machined on a plane surface (simple cycloidal groove that ball bearings roll in). Calculating the CNC files is simple. It is the superposition of 2 circular motions: one is once around, & the other is multiple times around. One plate has path where the 2 rotations are the same direction (makes cycloid) & the other opposite rotations (makes hypocycloid). The (larger) radius of the once-around rotation & the (smaller) radius of the multiple-times around rotations are the same on the 2 mating surfaces. You need 3 plates (2 surfece-sets) total. The center plate is forced to orbit by eccentric. The ratio between plate 1 & plate 2 is different than that between 2 & 3 & in the opposite direction. For example, if ratio 1 is 15:1 & ratio 2 is 16:1 (reversed), the total ratio of 240:1. I do have CAD files of one I made experimentally. If you have place where I can send them, I offer them for you to look at.

For future iterations: such high precision circular patterns should be made by indexing the workpiece with dividing head while keeping mill XY locked. Mill will always have some backlash and XY mismatch as well as XY perpendicularity error. All of these together will create hot mess when absolute position and circularity are important.

Around 1991 I was a young Elecromechanical Apprentis. I had been an Auto mechanic prior to working in the motor shop. I had a few worm gears, and several motors under my belt. My boss began freaking out, when he came in and saw 2 Cyclogears, completely dissassembled on my bench. Closest he ever came to screaming,, he yelled,, "We DON'T WORK ON CYCLOGEARS!! We Never have!" Not knowing,, I asked Why? Because you can't get them back together! Too complicated! He shouted! These were something in the 180 to 1. Ratio, multi stack. But low powered,, like 1.5hp used to extend/retract Gym Bleachers. He paced back and forth as I changed the bad bearings, and put them both back together. He calmed down, as we successfully test ran the first one. When he came back and saw the second one running fine, he said,, "Well I guess We work on Cyclogears."😊 dude you're good 👍! Cheers!

Arrived here from IM and have just hoovered up every minute of content you've so far put out. I've not done that amount of back-to-back KZfaq onsessive watching within the same day since I discovered Bobby Fingers. You're killing it - and making me realise that I need to embrace the Dunning-Kruger effect a little more in my own workshop. Nice one. Charlotte

So, I'm watching this man make a very complicated gearbox to remove backlash. But so far he hasn't mentioned why he NEEDS no backlash whatsoever. What application needs this design?

@indivisibleat0m 2 ай бұрын

I can't think of one offhand for something at home, but I've run into them at work for speed compensation gearboxes in printing where any backlash results in huge changes in print or cut quality

For some axis movement on his CNC machine. Any backlash will take your milling tool out of center

He should send the finished product to Elon Musk to fit into his rocket engines to reduce vibration.

What I need from a gearbox is some more alcohol. Love your vids 😊

I'll just make helical gears if I need no backlash.

Awesome engineering for someone who's ..... not an engineer! Though I was a little confused when you had PCB way machine the simple stuff, and you tackled the complicated high precision work in your shed. ??? By the way, what was the cost comparison of the PCB Way insert tool holders to the import sets? I've seen many KZfaqr's make tool holders but I have found that the import holders I have purchased are of extremely good quality, and I couldn't even buy the materials and hardware to make them myself for the cost of an import sets, let alone the incredible amount of work to make them. Great video as always! Regards.

Those holders worked out to about $70usd a piece, with shipping and customs, not including hardware. Of course that price comes way down if you're just getting bulk of one style. If I'd just gone with like 20 of the extended style, I think they'd be closer to $50USD. Worth playing around with their quoting system!

Mind you the import sets are a bargain, and totally fit for purpose. I just wanted a couple of special features. The extended holders make it much easier to use a live centre, and as far as I could see, there aren't any cheap alternatives the the $309usd aloris model

@@NoEngineerHereThanks. Yes, they are a bargain. The last 5 piece set of BXA holders came in at less than $14 usd each with all of the hardware, and were very nicely surface ground.

The effort and the cost just to send the parts to the Box of Shame (on the other side of the planet) is truly the sign of a great channel, and a great content creator. Subscribed.

Make the strain wave! It's still is somewhat difficult to achieve the necessary tolerance for zero backlash, but is more forgiving than cycloidals, which need precision grinding or wire EDM or waterjet laser. It does take some trial and error to get the flexspline thickness/stiffness right, and making an elliptical ball bearing would be difficult, but for a 4th axis you can just use a smooth ellipse. To make the flexspline, first machine the teeth and cup OD, then do the ID in many small Z steps so the material being cut is always well-supported and won't flex. Delrin is my favorite flexspline material. Low friction, resistant to fatigue and creep, and easy to machine (especially good for pancake style where the tooth face width is twice that of the split circular spline so you need a long skinny end mill). Another fun style is to turn the whole thing inside out, so the flexspline has internal teeth and is driven by a ring with elliptical inside diameter, and the circular spline(s) look like a gear with external teeth. Finding a good tooth profile for pancake style is difficult since the flexpline needs to engage with two gears of different tooth count but equal pitch diameter. I posted mine on imgur, but since youtube tends to delete comments with links you'll have to hack together an url yourself. The picture ID is 22jmHTF

Brilliant comment. I really would like to make a strain wave, and it'll be way easier with a rotary axis! Fyi there's a contact email on my about page 🤠

I love seeing “makers” make stuff on KZfaq, but what I love more is seeing makers make tools! There is something about seeing someone using tools to make tools that is weirdly satisfying! Thanks for the video!
